Fluorescent patterns of green fluorescent protein (GFP)-tagged microtubule-protein TUA6 (TUA6-GFP) microtubules marker in elongated petiole cells of transgenic Arabidopsis
thaliana. (A) Normal fluorescent pattern of TUA6-GFP as observed after treatment with low drug doses (here 0.1 mg/L, 0.26 µM kiteplatin); (B) Perturbed microtubules after treatment with 1 mg/L, 2.5 µM, oxaliplatin; (C) Weak perturbation of microtubules orientation after treatment with 5 mg/L, 13 µM, kiteplatin; (D) Strong alteration due to treatment with 200 mg/L kiteplatin; (E) Clear alteration of TUA6-GFP distribution after treatment with 1 mg/L (3 µM); and (F) 200 mg/L (67 µM) cisplatin. Scale bar: 20 µm.
